It connects two sections of threaded pipe with a female NPT (FNPT) end style on both sides and uses a ground joint seat to create a leak-resistant metal-to-metal seal. The three-piece union design allows the pipe assembly to be broken apart and reconnected without disturbing the surrounding piping. It is installed by licensed plumbers and pipefitters on gas, water, and general-service piping systems where routine disconnection of a pipe run is required.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial plumbing and gas piping applications. The galvanized finish provides corrosion resistance in exposed or semi-exposed installations such as mechanical rooms, utility spaces, and above-grade pipe runs. The 1\/2 inch nominal size fits standard Schedule 40 threaded pipe and is a common fitting in low-pressure domestic water and gas distribution systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGround joint seat provides a metal-to-metal seal without requiring a gasket\u003c\/li\u003e\n\u003cli\u003e150 lb pressure rating suitable for standard plumbing and gas service\u003c\/li\u003e\n\u003cli\u003eGalvanized malleable iron construction resists corrosion in damp environments\u003c\/li\u003e\n\u003cli\u003eFNPT threads on both ends accept standard NPT-threaded pipe\u003c\/li\u003e\n\u003cli\u003eThree-piece design allows the pipe run to be disconnected and reconnected at the union\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1\/2 inch nominal NPT threaded pipe systems in residential and commercial plumbing and gas piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements. Shut off and depressurize the pipe system completely before removing or installing any union. Apply thread sealant or pipe tape appropriate for the service medium to all male NPT threads before assembly. Do not over-tighten the union nut, as malleable iron threads can be damaged by excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3463\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIGMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 813508009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525350621490,"sku":"GALU12I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0211824fb5b74af7a4106487a55dca8e_472c2f18-422e-40e6-885f-f5b519b5888c.jpg?v=1785471275","url":"https:\/\/voomisupply.com\/products\/sigma-813508009-ground-joint-pipe-union-1-2-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
